The harrowing CCTV from BZR in Nottingham shows the six-inch blade being plunged into the back of defenceless Matthew Withers, 31.

Mr Withers had to be treated on the bar, and later needed life-saving surgery to survive the cowardly attack by thug Jordan Hamilton.

Cameras recorded the chilling moment Hamilton slammed his blade into the back of Mr Withers, puncturing his lung.

The ordeal has affected him so deeply, he now wears a stab vest to work.

The 21-year-old attacker was jailed for four years last week for a frenzied spate of stabbings.

ATTACK: Hamilton's frenzied stabbing left two injured

“It still affects me. I was walking through the city recently and walked past a group of lads and it made me nervous”

Callum Northridge, 27, was knifed in the buttocks and twice in the leg by the yob as well on April 6 this year.

The club confontation later spilled on to the dancefloor and then out onto the streets.

Both victims slammed the "joke" sentence handed out to the attacker and called for tougher penalties on knife crimes.

Mr Withers said: "I'm only here because of the operation I had.

"I had about a month off work and it made me think about carrying on doing my job, which is a shame because I enjoy it.

CARNAGE: The melee which ensued at the Nottingham club

"I've had to buy a stab vest to wear to work. It still affects me. I was walking through the city recently and walked past a group of lads and it made me nervous.

"I just want to know why he did it and why he had the knife. Why he feels like he needed to have a knife in Nottingham.

"The sentence for carrying a knife is five years, and he used one to stab two people but still only got four years. It should be more.

"I feel like the justice system has let me down."

Plumber Callum, who can be seen in the CCTV clutching his leg by the bar after being stabbed, added: "I was told if the stab wound on my leg was an inch away from hitting the main artery in my leg.

"If that happened, it means almost certain death.

TREATMENT: The bouncer is given medical care while leaning on the bar

"In the CCTV, he swings at me with the knife and I had done a pretty pathetic kick, but it probably saved my life."

Callum said the incident had also had a profound effect on his wife, Hayley, who was eight-and-a-half months pregnant at the time.

He added: "She went into labour early because of the stress, and I didn't want to be in hospital because she was pregnant.

"I still feel numb in my calf, I'm not sure why, and for the first few weeks when my daughter was born, I couldn't even hold her."

Co-accused Robert Watson, of Beeston, Notts, was jailed for 20 months for causing GBH to another doorman on duty that night.

PROBE: Police were quick to cordon off BZR

James Savage, 29, of Bulwell, Nottingham, was convicted of causing actual bodily harm inflicted on two door staff and will be sentenced at a later date.

Detective Inspector Rob Wells, from Nottingham Police, said: "Jordan Hamilton, a young man with no convictions and of previous good character, chose to arm himself with a knife and used it to cause injury to two people, one of whom was seriously injured and is still suffering the effects of the assault.

"He now has the next four years to consider how a thoughtless action has dramatically changed the course of his life."

Hamilton was sentenced at Nottingham Crown Court on Friday after admitting wounding with intent to cause grievous bodily harm and wounding.
